TO -ALL WHOM I 'l MAY CON CERN:

Beit known that I, S. T. McDUGALL, of Brooklyn, Kings county, New York, have invented, made, and applied t'ouse,"a new and useful Clothes-Pounder; and I do 'declare the following to be a full, clear, and exact description thereof, reference being. made to the accompanying drawings, making lpart of this specification, and to the letters of reference marked thereon, in which- Figure 1 is a View of my improved clothes-pounder, the pounder being down. Figure 2 is a view of the saine, .the pounder being shown elevated. In the drawings, like parts of-the invention are designated by the same lettersof reference.

The natureof my invention consists in certain improvementsn'as more fully hereinafter set forth, inthe construction and operationvof a clothes-pounder.

To enable those 'skilled lin the arts te make andfuse my invention, I will describe the construction and operation of the same.

A is a frame, for supporting the operating .parts of my clothes-pounder, and'B is a box, in which the clothes to he pounded are placed, and within which box the pounders and piishers, alluded to hereinafter, operate- C is a driving-shaft, held in position in the frame by journals, and having secured upon it, about centrally, the-cams D D, intended to operate the pounder E. y l

-Eshows the pounder for pounding the clothes, secured upon the lower or bottom end of a rod, F, the upper end of which rod is free to play in an opening in the cross-brace of the frame A.

This rod has securedupon it, near its upper end, and so that it shall be directly above the cams D2 lipon the driving-shaft, athimble, G, upon the under side of whichiitl is intended the cams shall impinge.A

The rod has also secured upon it a circular plate ordisk, H, which plate or disk, when the rod is raised, is brought into contact with the lugs/J secured upon the upper ends ofthe arms K.'

These arms `K are pivoted within the slotted projections L upon the frame A, and have attached to their lower ends the pushers M, which consist of the fiat slotted'blocks of wood, slotted as shown, to admitof their attachment to r the lower ends of the arms K, and also of their free movement, either up or down, when the machine is in operation.

N are springs, passed around or secured in any convenient manner to the arms K, and intended to withdraw the pushers'M, as more fully` hereinafter described.

Such being the construction, the operatiop may be thus set forth: The'clothes to beipounded are placedin the box B, partially iilled with water, and the shaft C may be provided 'within-handle, 'or may be connected to any convenient motor.

As the shaft revolves, the cam l) impinges upon the under side of the thimhle G, secured upon the rod F, raising the rod F, and` at the same time giving to the same, as` raised, a part rotary motion.

As the rod is raised, the disk or circular plate H is brought into contact with the lugs Jupon the upper ends of the arms K, throwing the same back, a'n'd the lower ends, to which are attached the pushers M forward.

These pushers thusV crowd forward the clothes' to be pounded, sethat they'shall, just before the descent of the pounder E, be brought directly beneath it.-

As the shaftcontinues its revolutions, the cam D ceases te impinge upon the under side of the thimble G,v

and the rod-F drops or descends,

As the rod drops or descends, the plateor disk H is relieved from the lugs upon the upper rends of the arms K, and the springs N, attached as shown, and previously expanded by the upward movement of the rod F, now contract, returning to their original position outside of the pounderV E, the pushers M, which, in their forwardA movement, have crowded forward the clothes contained in the box B.

The shaft continuing to revolve, the cam l)2 is brought into contactwith the under surface of the thimble G, and the operation just described is repeated.-

Thus it will be seen that in the. present invention I obtain a reciprocating or a part rotary movement for carrying with it the pounder E, which is thus brought down upon the clothes.'

the rojd to which is attached the pounder, and at the i same ltime give to the pushers a forward movement, and that these movements are all` due to the peculiar construction of the cams D and D2, upon the driving-shaftand of the arms supporting the pushers.

The usefulness of the machine. is materially increased by the presence of 'the pushers, tending, as they do, to crowd all the clothes up beneath the pounder, 'Vwlil the partrrevolution imparted to the pounder renders the y operation of the same most thorough.

The low cost of manufacture of the' machine, with its thorough working, renders the same particularly desirable. I

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is-

1. The pushers M, connected to the arms K, and operated substantially as4 described, for the purposes sei; forth; i

2.. In combination with the same, I claim the pounder E, when the same shall be constructed and operated substantially as described, for the purposes set forth.
